-/**
- * @class ACE_Timeprobe_Ex
- *
- * @brief This class is used to instrument code. This is accomplished
- * by inserting time probes at different location in the code.
- * ACE_Timeprobe then measures the time difference between two
- * time probes.
- *
- * This class provides a lightweight implementation for
- * measuring the time required to execute code between two time
- * probes. When a time probe executes, it records the time, the
- * id of the calling thread, and an event description. The
- * event description can either be an unsigned long or a string
- * (char *). If string are used, care must be taken cause only
- * pointer copies are done and the string data is *not* copied.
- * The recorded time probes can then be printed by calling
- * <print_times>. If you have used unsigned longs as event
- * descriptions in any of your time probes, you must have
- * provided an event description table that maps the unsigned
- * longs to readable strings. This map is a simple array of
- * strings, and the event number is used as the index into the
- * array when looking for the event description. If you have
- * only used strings for the event description, this map is not
- * necessary.
- * Multiple maps can also be used to chunk up the time probes.
- * Each one can be added by calling <event_descriptions>.
- * Different tables are used internally by consulting the
- * minimum_id for each table. It is up to the user to make sure
- * that multiple tables do not share the same event id range.
